SPECIFICATION forming part of Letters Patent No. 500,113, dated June 27,1893.

Application filed October 11, 1892. Serial No. 448,524- (No model.)Patented in England April 15, 1891, No. 8,444.

To all whom it may concern..-

Be it known that we, WILLIAM HALL (3001; and JAMES HARRISON, subjects ofthe Queen of Great Britain, residing at Manchester, in

the county of Lancaster, England, have invented certain new and usefulImprovements in Apparatus for Imparting a Variable Motion to theTraverse-Rods in Machines for Preparing and Spinning Fibrous Materials,

[0 (for which we have obtained Letters Patent in Great Britain, No.6,444, bearing date the th day of April, 1891,) of which the followingis a specification.

This invention is designed to produce a re- 15 ciprocating motionvarying in the distance traveled at each stroke or varying the pointupon which the direction of movement changes at the end of each stroke,to be applied to the traverse or traverse rod of spin- 2o ning or othersimilar frames, with the object of preventing the wearing of grooves in,or the cutting of the leather covered rollers between which the rove orsliver of material passes.

It consists essentially in constructing the apparatus with twoindependent eccentrics which act independently of each other through twoseparate links or connecting rods affixed to a bracket pivoted to thetraverse rod.

0 It will be fully described with reference to the annexed drawingswhich show apparatus constructed in accordance with the invention;

Figure 1 is a front elevation; Fig. 2, back elevation; Fig. 3,-pla'n;Fig. 4, transverse sec- 3 5 tional elevation through the eccentrics online w0c,' Fig. 5, transverse sectional elevation on line y-y; Fig. 6,front elevation of modified form or arrangement of the apparatus; Fig.7,

back elevation of same ,Fig. 8, plan of same 3 40 Fig. 9, transversesectional elevation on line w-w; Fig. 10, transverse sectional elevationon line z-z.

On a fixed bracket A placed on the roller beam or other convenientposition in the ma- 5 chine, we mount two separate eccentrics B Bworking independently of each other, and

each fitted with a connecting rod or link 0 C by which the motion of thetwo eccentrics is conveyed to a common bracket D, pivoted to thetraverse rod E. Each of the eccentrics we prefer to form on the side ofa toothed wheel which receives motion from a worm or other gear, and bywhich they are rotated.

Referring more particularly to Figs. 1 to 5, the two eccentrics B B areeach formed on the face of a worm wheel F F and are mounted side by sideon a stud f carried by the fixed bracket A. The two worm wheels vary insize by one or more teeth so that their relative position and that ofthe eccentrics is constantly varying. On the traverse rod E, is pivotedthe bracket D, to which both eccentrics are connected by the rods orlinks O O. The bracket is pivoted at one end to the traverse rod, and atits other end is 55 pivoted the connecting rod 0', the connecting rod Cbeing pivoted to it by a separate pivot at a convenient distance fromthe bottom of the bracket. The bracket D is provided with a longitudinalslot at its upper end, and is connected to the traverse rod E by a studd, the position of which is adjustable in the slot. The stud d is fastto the bracket 1) and pivoted or free to rotate in the bracket e fittedto the traverse rod E. The ends of the connecting rods are each pivotedon studs 0 0' made fast in transverse slots. The throw or length oftraverse of the rod E can be regulated or adjusted as required byaltering the position of the studs (1,0 or c in their respective slots,so as to give a longer or shorter extreme traverse. The wheels F F aredriven by the Worm G cut in or fixed upon the roller or by any othersuitable arrangement.

Referring more particularly to Figs, 6 to 10, the same description willin most part apply to the modified form of the apparatus, but instead ofboth eccentrics B B and their respective wheels being mounted on thesame stud or center, they are mounted upon separate studs, and the wheelF' driven from a wheel F connected to the worm Wheel F, as by this meansgreater variation or difierence in the speed of the two eccentrics B Bcan be obtained. In the drawings a star or stud Wheel is shown at Fconnected to the eccentric B, which is actuated by a stud or projectionf" on the wheel F by which the wheel F, and eccentric B are moved forthebracket D in the same direction, and at another time one eccentric willbe throwing its connecting rod in one direction, and the other eccentricits connecting rod in the 0pposite direction, thus communicating aconstantly varying traverse to the end of the bracket D and traverse rodE. In the second example, the constant movement to the traverse rodisefiected by the eccentric B and connecting rod 0 while the end of theconnecting rod 0' acts as a fulcrum, the position of which is altered ateach revolution of the eccentric B by the movementgiven to the eccentric13 thus communicating a varying motion to the end of the bracket D fixedor connected to the tra'verse rod E.

We wish it to be understood that we are well aware that two eccentricshave been used to vary the traverse where one eccentric has been placedinside the other or to act directly upon the other, and that such havebeen actuated by two worm wheels of diiferent diameter gearing togetherinto a single worm, and we do not make any claim therefor.

What we claim as our invention, and desire to protect by Letters Patent,is-

1. An apparatus for imparting a variable motion to the traverse rod ofpreparing and spinning machines provided with two independent eccentricsworking separately and two separate connecting links through which themovement of the eccentrics is independently transmitted through a commonbracket to the traverse rod in combination with a common bracket towhich they are pivoted, the traverse rod to which the bracket isattached, and the worm wheels and worm which actuate the eccentricssubstantially as described.

2. In apparatus for imparting a variable motion to the traverse rod ofpreparing and spinning machines the combination with the traverse rod'of two separate independent eccentrics the relative positions of whichare constantly changing, two separate independent connecting rodsthrough which the movementof the eccentrics is transmitted, two wormwheels afiixed to the eccentrics,a-worm aifixed to the roller shaft anda common bracket attached to the traverse to which the connecting rodsare attached in differentpositions substantially as described.

3. In apparatus for imparting a variable motion to the traverse rod ofpreparing and spinning machines, the combination of the two separateindependent eccentrics B B which work independently of each other, theworm wheels F F which are attached to and actuate the eccentrics, thetwo separate links or connecting rods 0 0 through which the movement ofthe eccentrics, is transmitted and the bracket D affixed to the traverserod common to the two connecting rods, with the 'worm G on the rollerand the traverse rod E substantially as described.

4. In apparatus for imparting a variable motion to the traverse rod ofpreparing and spinning machines, the combination of the traverse rod E,the actuating worm G on the roller, the bracket A, the worm wheels F Fwhich are attached to and actuate the eccentrics,the independenteccentrics B B, the stud f which carries the eccentrics, the twoseparate connecting rods 0 C which transmit the movement of theeccentrics, the bracket D to which the two connecting rods are attachedin diiferent positions, the studs 0 c with which the ends of'theconnecting rods engage and the bracket 6 provided with stud d by whichthe bracket D is attached to the traverse rod.
